Golang Tutorial
Master Golang in 3 days. This tutorial is:
- Easy reading.
- Example based. Every concept comes with a standalone runnable code.
- Correct.
- Direct. No nonsense, no personal story telling.
- No elite hacker jargons. (such as about compilers, references, garbage collection. They are discussed only when necessary from program behavior point of view.)
